The study of the functions an organism performs
physiology
A circulatory system with no opening to the outside
The balance in the uptake and loss of water and solutes
Osmoregulation
Lymphocytes primarily involved in the production of antibodies
B-cells
The basic contractile unit of a muscle fiber
Sarcomere
The four basic types of tissues
epithelial, connective, muscles, nervous
The vessel that leads from the heart to the lungs
The pulmonary artery
Where water is passively pulled out of the nephron
The descending loop of henle and collecting duct
Cytokines from helper t-cells
A guard that blocks myosin-binding sites
Tropomyosin
The steps of basic food processing
ingestion, digestion, absorption, elimination
Plays a major role in the electrical impulses in the heart
Purkinje fibers
Filters the blood in the nephron
The glomerulus
The part of the neuron that receives a signal
The dendrites
Types of asexual reproduction
fission, parthenogenesis, fragmentation, budding
Covers the trachea so food can't pass through
The epiglottis
Controls our breathing
The diaphragm and medulla oblongata
Major endocrine glands
Hypothalamus, post. pituitary, ant. pituitary
Makes the myeline sheath
Schwann cells
The gamete development of an egg
oogenesis
Where fats are digested
The lumen of the small intestine
The end of the bronchioles that diffuse gases into and out of the blood
The alveoli
A pathway where the stimulus binds to a receptor protein on an endocrine cell first
Simple endocrine pathway
Channels that open to allow sodium and potassium into the neuron during action potential
Voltage-gated ion channels
Produces eggs in females
