Q
PHYSIOLOGY
A
is the study of the functions of the systems and structures of the human body.
25
There are 6 essential life functions or processes that a cell carries out:
respiration , Responds to stimuli, Reproduction, metabolism, Anabolism , catabolism , movement
26
Anabolism
- the process of building up larger molecules from smaller ones. During this phase, the body stores water, food and oxygen.
27
Catabolism
- the process of breaking down larger molecules or substances into smaller ones. This releases energy within the cell, which is necessary for the performance of specific body functions, including muscular movements and digestion.
28
5 types of tissue
Epithelial tissue, connective, nervous, muscle, liquid
29
Epithelial tissue
covers and lines body surfaces and internal organs.
30
Connective tissue
supports and holds body parts together. Examples are the dermis of the skin, bone, and cartilage.
31
Nervous tissue
controls body activities and allows for sensation and reaction. Examples are the brain, spinal cord and nerves.
32
Muscle tissue
contracts and expands when stimulated to produce movement. Examples include skeletal muscles.
33

Comprises the skin, hair, nails, and associated glands. It protects the body, regulates temperature, and provides sensory information.
70
The Cardiovascular System
Consists of the heart, blood vessels, and blood. It transports oxygen, nutrients, hormones, and waste products throughout the body.
71
Erythrocytes (Red Blood Cells)
Cells in the blood that carry oxygen from the lungs to the body's tissues and return carbon dioxide back to the lungs. They contain hemoglobin, a protein that binds oxygen.

Arteries
are elastic, thick walled vessels. They carry oxygenated blood away from the heart to the body tissues.
75
Veins -
are less elastic and thinner than arteries. They carry deoxygenated blood from the body tissues back to the heart; they contain valves to prevent backflow.
76
Capillaries -
are tiny, thin walled vessels. They join small arteries to small veins and allow for the diffusion of nutrients, wastes and oxygen.
77
Lymphatic System
This system circulates lymph, a straw-coloured fluid that originates from blood plasma. It includes lymph, lymph vessels, lymph glands and lymph nodes; it does not include a pump, like the heart. Lymph travels through lymph capillaries and re-enters the blood vascular system in the chest area (terminus). Lymph nodes act as filters for the body where the lymph, containing white blood cells, fights infection.
78
Neuron
is specially designed to receive and carry electrical and chemical impulses. Each has three important parts:
● Soma - the body of the cell.
● Dendrites - extend from the soma and pick up impulses from other nerve cells.
● Axon -the thread like extension that carries an impulse along to the synaptic bulb.
79
sensory nerve
A type of nerve that carries sensory information (e.g., touch, temperature, pain) from the body to the brain and spinal cord.
80
Motor Nerve
