Anatomy and Physiology 12 Topics PDF

**Anatomy and Physiology \-\-\--12 Topics** **Topic 1**- General Surgy #### Gastrointestinal Tract (GI Tract) - **Also called the alimentary tract.** - Includes the **esophagus, stomach, small intestines, large intestines, and rectum.** - Functions: **Ingestion, secretion, digestion, and absorption** of food and nutrients. **The Basic function of the GI tract** #### Esophagus - **Transports food** from the pharynx (throat) to the stomach using **peristalsis** (muscle contractions). - **EGD (Esophagogastroduodenoscopy):** A procedure to scope the esophagus, stomach, and duodenum. - **Endoscopes** must be disinfected thoroughly. - Instruments like biopsy forceps must be sterile. - **GERD (Gastroesophageal reflux disease):** Stomach acid flows back into the esophagus, causing pain and heartburn. - **Barrett\'s Esophagus:** Abnormal cell growth in the esophagus, can lead to cancer. - **Esophagectomy:** Removal of a part of the esophagus, can be done through different surgical techniques. - **Zenker\'s Diverticulum:** A pouch that forms in the esophagus wall, which can collect food and cause a sensation of fullness. - **Esophageal Hiatal Hernia:** Part of the stomach pushes through the diaphragm into the chest. - **Laparoscopic Nissen Fundoplication:** Surgery to wrap the stomach around the esophagus to prevent acid reflux or Reflux disease.. - **Esophageal Dilation:** A procedure to widen a narrowed esophagus, often after scarring from surgeries or burns. #### Stomach ### Stomach Functions - **Location**: Upper left abdomen, between the **esophagus** and the **duodenum**. - **Stores food**: Temporarily holds food before it is passed into the small intestine. - **Digests food**: Uses **acids** (like hydrochloric acid) and **enzymes** (such as pepsin) to break down food, especially proteins. ### Surgical Procedures Involving the Stomach - **Vagotomy**: A surgical procedure where the nerves that stimulate stomach acid production are cut. This is often used to treat ulcers that do not respond to medication. - **Pyloroplasty / Pyloromyotomy**: These procedures are performed to widen the **pylorus** (the exit of the stomach), improving food passage. Often done for infants with a condition called **pyloric stenosis**, where they have difficulty feeding and frequent vomiting. - **PEG (Percutaneous Endoscopic Gastrostomy)**: A feeding tube is placed directly into the stomach through the abdominal wall. This is commonly done for patients who cannot eat normally, either for nutrition or to decompress the stomach. - **Gastrojejunostomy**: A procedure where the stomach is connected to the **jejunum** (the second part of the small intestine) to bypass blockages, often due to conditions like cancer. - **Gastrectomy (Partial or Total)**: The removal of part or all of the stomach, commonly performed for patients with stomach cancer. A **partial gastrectomy** removes part of the stomach, while a **total gastrectomy** removes the entire stomach. - **Bariatric Surgery (Weight Loss Surgery)**: These procedures reduce the size of the stomach to help treat obesity. Common types include **gastric bypass** and **sleeve gastrectomy**, which limit the amount of food that can be eaten and absorbed. **Functions of the Digestive System:** 1. **Ingestion**: - The process of taking in food and liquids through the mouth. This is the first step of digestion where food enters the body. 2. **Secretion**: - Various parts of the digestive system release fluids to aid digestion, including: - **Saliva** from the salivary glands, which contains enzymes that begin breaking down carbohydrates. - **Gastric juices** from the stomach, including hydrochloric acid and enzymes like pepsin, that digest proteins. - **Bile** from the liver, stored in the gallbladder, which helps break down fats. - **Pancreatic enzymes** that further digest carbohydrates, proteins, and fats in the small intestine. 3. **Digestion**: - This is the breakdown of food into smaller molecules that can be absorbed by the body. It involves: - **Mechanical digestion**: Chewing in the mouth and churning in the stomach. - **Chemical digestion**: Enzymes and acids breaking down complex molecules into simpler nutrients. 4. **Absorption**: - The process by which nutrients from digested food are absorbed into the bloodstream through the walls of the small intestine. - **Carbohydrates** are broken down into simple sugars. - **Proteins** are broken down into amino acids. - **Fats** are broken down into fatty acids and glycerol. - Water and some vitamins and minerals are absorbed in the **large intestine**. #### Small Intestine - **Parts:** - **Duodenum**, - **Jejunum**, - **Ileum**. - **Function:** Absorbs nutrients from digested food. - **Ligament of Treitz:** Connects the duodenum and jejunum. - **Meckel\'s Diverticulum:** A congenital pouch in the intestine, can cause bleeding or obstruction. - **Intussusception:** One part of the intestine slides into another, causing blockages. #### Large Intestine - **Starts at:** Ileocecal valve, - **Ends at:** Anus. - **Parts:** - **Cecum** (with appendix), - **Colon** (ascending, transverse, descending, sigmoid), - **Rectum, Anus**. - **Functions:** Reabsorbs water, helps eliminate solid waste. - **Appendectomy:** Removal of the appendix, often for appendicitis. Special techniques are used to prevent infection. - **Bowel Technique:** Instruments used during bowel surgery should be isolated to prevent contamination. #### Intestinal Surgeries - **Intestinal Stomas:** Creating an opening (stoma) to divert stool, e.g., ileostomy, colostomy. - **Hemicolectomy/Colectomy:** Removal of part or all of the colon. - **Whipple Procedure (Pancreaticoduodenectomy):** Removal of parts of the pancreas, stomach, duodenum, and other organs, often for cancer treatment. #### Retum The ***rectum*** plays a crucial role in the body's digestive and excretory systems. The rectum is the final portion of the large intestine in the digestive system. It serves as a temporary storage site for feces before they are expelled from the body through the anus. The rectum is about 12 centimeters (4.7 inches) long and connects the sigmoid colon to the anal canal. Key functions of the rectum include: - **Storage**: It holds stool until defecation occurs. - **Sensory Role**: The rectum contains nerves that signal to the brain when it\'s time to release waste. - **Elimination**: During defecation, muscles in the rectum and anus relax to allow stool to pass out of the body. It\'s an important part of the body\'s waste management system. #### Biliary System (Gallbladder) - **Gallbladder (GB):** Stores bile for digestion. - **Cholecystectomy:** Removal of the gallbladder due to gallstones or inflammation. Can be done laparoscopically. - **ERCP:** A procedure to identify and remove stones or blockages in the bile ducts. - **Cholangiogram:** X-ray to view bile ducts using dye. #### Liver - **Location:** Upper right abdomen. - **Functions:** Produces bile, processes nutrients, and detoxifies the body. - **Liver Resection:** Removal of part of the liver, often for tumors. - **Liver Transplant:** Replaces a diseased liver with a donor liver. #### Spleen - **Location:** Upper left abdomen(hypochondriac) - **Splenectomy:** Removal of the spleen, often for trauma or diseases like sickle cell anemia. #### Pancreas - **Location:** Behind the stomach, produces digestive enzymes and insulin. - **Whipple Procedure:** Removes parts of the pancreas, stomach, and duodenum, usually for pancreatic cancer. - **Pancreatectomy:** Removal of part or all of the pancreas. #### Hernias - **Hernia:** Protrusion of an organ through a weak spot in the abdominal wall. - **Types:** - **Inguinal (groin)**, - **Umbilical (belly button)**, - **Ventral (abdominal wall)**, - **Hiatal (diaphragm)**. - **Hernia Repairs:** Often involve sutures or mesh to close the weakened area. Can be open or laparoscopic surgery. #### Breast Surgery - **Mammogram:** X-ray of the breast to detect cancer. - **Breast Biopsy:** Removing a sample of tissue for testing. - **Lumpectomy:** Removing a tumor while saving the rest of the breast. - **Mastectomy:** Complete removal of the breast for cancer. - **Sentinel Lymph Node Biopsy:** Tests to see if cancer has spread to nearby lymph nodes. - **Breast Reconstruction:** Surgery to rebuild the breast after mastectomy. #### Surgical Incisions - **Midline Incision:** Used for abdominal surgeries. - **Pfannenstiel Incision:** Low horizontal cut, often used for pelvic surgeries (e.g., C-sections). - **McBurney Incision:** For appendectomy (removal of appendix). - **Kocher Incision:** Subcostal cut for gallbladder surgery. - **Laparoscopic Surgery:** Minimally invasive surgery with small incisions and use of a camera. ### ### ### ### Layers/ wall of the Intestine: - Serosa-Outer layer - Muscularis - Submucosa - Mucosa-Inner layer ###
