Study Notes
Hemoglobin
- Hemoglobin is a naturally colored red pigment.
- It appears red when combined with oxygen and bluish when deoxygenated.
- Hemoglobin carries oxygen from the lungs to the tissues.
Sensory System
- A sensory system consists of sensory neurons, including sensory receptor cells, neural pathways, and parts of the brain involved in sensory perception.
Motor Nervous System
- The motor nervous system generates voluntary movement and sends the motor plan via descending tracts to the effector muscles.
Homeostasis
- Homeostasis is the body's ability to resist changes in the internal environment but has a variable range and time.
- Most diseases are caused by a failure of homeostasis.
Digestion
- Digestion is accomplished by enzymes that hydrolyze certain bonds in food molecules, releasing simple molecules.
- The function of the digestive system is to mix food with digestive juices, helping digestion and absorption.
Thyroid Hormone Function
- Increases heat production (calorigenic effect).
- Increases myocardial contractility.
- Important for nervous system development.
- Helps in growth.
- Causes protein catabolism.
Pulmonary Functions
- Pulmonary endothelial cells secrete angiotensin converting enzyme (ACE).
- ACE converts angiotensin I into angiotensin II.
- The lungs defend the body against inhaled foreign matter through:
- Cilia
- Phagocytes
- Mucus Secretion
- Inspiration is the movement of air from the atmosphere to the alveoli.
- Expiration is the movement of air from the alveoli to the atmosphere.
- The normal respiratory rate is 12-16 breaths per minute.
Cellular Functions
- Cells perform essential functions for survival:
- Obtaining nutrients
- Eliminating waste
- Synthesizing cellular components
- Responding to environmental changes
Cardiac Output Factors
- Sympathetic stimulation increases cardiac output.
- Parasympathetic stimulation decreases cardiac output.
- Catecholamines and thyroxin increase cardiac output.
Pancreas Functions
- The pancreas has two major functions:
- Exocrine: secretes digestive juices
- Endocrine: releases hormones
Pancreatic Hormones
- Insulin - lowers blood glucose levels.
- Glucagon - raises blood glucose levels.
- Somatostatin - regulates secretion of insulin and glucagon.
Diabetes Mellitus
- Diabetes mellitus is a metabolic disorder characterized by hyperglycemia due to either a deficiency of insulin or a decreased responsiveness to insulin.
Respiratory System
-
The respiratory system can be divided into the upper and lower respiratory tracts
-
The upper respiratory tract includes the nose, pharynx, and larynx
-
The lower respiratory tract includes the tracheobronchial tree
Hemolytic Anemia
- Hemolytic anemia occurs when there is excessive rupture of circulating erythrocytes
Hemorrhagic Anemia
-
Hemorrhagic anemia is caused by excessive blood loss
-
Acute hemorrhagic anemia can occur from bleeding from a wound
Immune Functions of Digestive System
- The gut wall contains lymphoid tissue that participates in immune reactions
Digestive System Function
- The digestive system functions through 4 basic processes: secretion, motility, digestion, and absorption
Control of Gut Functions
-
Gut functions are controlled by neural regulation
-
The enteric nervous system controls the functions of the gut
- It is a network of neurons in the wall of the gut
- Also known as "the brain of the gut"
Functions of the Parathyroid Gland
-
It is the major regulator of calcium concentrations in body fluids
-
The main function of parathyroid hormone is to increase plasma calcium concentration
The Immune System
- The immune system can be divided into two parts: the natural (innate or non-specific) immune system and the acquired (specific) immune system.
Negative Feedback
- Negative feedback is a process where the response of a system is antagonistic to the stimulus (disturbance).
- Any change in a quantity from its set value triggers a response that aims to restore the quantity back to its original value.
Cardiovascular System
- The aorta originates from the left ventricle and its opening is guarded by the aortic valve.
- The pulmonary artery originates from the right ventricle and its opening is guarded by the pulmonary valve.
Digestive System
- Bile salts are crucial in fat emulsification.
- Bile salts break down large fat globules into smaller ones, making them easier to dissolve in water.
- This process increases the surface area of fat droplets, facilitating digestion by pancreatic lipase.
Female Reproductive System
- Puberty marks the onset of menstrual cycles.
- These cycles continue until menopause.
- The duration of each menstrual cycle varies between women, with an average duration of approximately 28 days.
Blood Transfusion Incompatibilities
- Can lead to pain, jaundice, and acute renal shutdown
Mechanical Overloading
- Can occur with blood transfusions, especially in patients with cardiac diseases
Blood Volume
- Average blood volume:
- Male: 60%
- Female: 55%
- Infant: 75%
- Fetus: 97%
Water Balance:
- Normal fluid intake: 2-3 L/day
- Sources: Drinking, Eating, Oxidation of food
Gut Motility
- Movement of food through the digestive tract is controlled by smooth muscle contraction
- It can be regulated independently of the autonomic nervous system
- Types:
- Propulsive (peristaltic) movement: Moves food forward
- Autonomic nerves:
- Sympathetic: Controls overall body functioning
- Parasympathetic: Stimulates intestinal activity
Small Intestine Function
- Contains digestive enzymes that complete carbohydrate and protein digestion
- Enzymes: Peptidases and disaccharidases
- Digested food is absorbed in the small intestine
Dual Innervation
- Most organs are innervated by both sympathetic and parasympathetic nervous systems.
- Exceptions: Skin, sweat glands, spleen, skeletal muscle blood vessels, and the adrenal glands are only innervated by the sympathetic nervous system.
Somatic and Autonomic Nervous Systems
- The nervous system is divided into somatic and autonomic nervous systems.
- The somatic nervous system controls voluntary movements.
- The autonomic nervous system controls involuntary processes within the body.
