Study Notes

Abdominal Organs in Dissection

Dissections of a rat and human cadaver provide insights into abdominal anatomy, with structures labeled for learning purposes.
Cecum: The first part of the large intestine, located at the posterior abdominal wall.
Kidneys: Bean-shaped, retroperitoneal organs (located behind the peritoneum) responsible for waste filtration.
Rectum: End segment of the large intestine leading to the anus, also covered partially by the urinary bladder.
Adrenal glands: Endocrine glands positioned atop each kidney, vital for metabolic regulation.
Anus: The digestive tract's external opening found at the end of the anal canal.

Organ Systems Overview

The human body comprises 11 organ systems, each with specific functions and major organs.
Human organ systems work collectively to maintain homeostasis and support physiological functions.
Cells are the basic unit of life, organized into four primary tissue types: epithelial, muscular, nervous, and connective.
Tissues consist of similar cell types working together, while organs are structures made of multiple tissue types for specific functions.
Organ systems are composed of groups of organs collaborating to execute vital body processes (e.g., digestive system).

Dissection Techniques and Tools

Preparation involves using various tools such as scissors, forceps, and dissecting pins to explore anatomical structures.
The diaphragm separates thoracic and abdominal cavities, accessible through lateral cuts and careful handling.
Key structures identified within the thoracic cavity include:
- Esophagus: Connects pharynx to stomach, vital for food transportation.
- Heart: Enclosed in pericardium, responsible for circulation.
- Lungs: Flank the heart, essential for respiration.
- Trachea: The windpipe leading to the bronchi, part of the respiratory system.

Examination of the Ventral Body Cavity

Start from superficial to deep structures when examining the thoracic cavity, referencing visual aids.
Identification of key organs follows sequentially from digestive and respiratory systems, highlighting interconnections.
Observations include the path of the digestive tract from stomach to intestines, encompassing small and large intestines ending at the anus.
