| Question | Answer |
|---|---|
| What are the three major steps in urine formation | filtration (glomerulus) Reabsorption (tubules) Secretion (distal Tubule/collecting duct) |
| Where does filtration occure in the kidneys? | The glomerulus inside the renal corpuscle |
| What hormone increases water reabsorption in the kidneys | ADH Anti diuretic hormone |
| What hormone reduces blood volume and pressure by increading urine output | ANH/ANP Atrial Matriuretic Hormone/peptide |
| What is the primary function of the loop of Henle | Concentrates urine by creating a countercurrent gradient |
| What is the master gland of the endocrine system | The Pituitary gland |
| The difference between the endocrine and exocrine glands | Endocrine secretes hormones into blood; exocrine secretes substances through ducts |
| What hormone regulates metabolism | Thyroid hormone |
| What hormone is low in diabeties Mellitus | Insulin |
| Where does gas exchange occure in the lungs | Aveoli |
| What is tidal volume | the amount of air being inhaled or exhaled during normal breathing |
| What is expiratory reserve volume (ERV) | Additional air that can be forceable exhaile after a normal exhale |
| Muscle responsible for breathing | The diaphram |
| Something that drives oxygen diffusion into the blood | A higher oxygen concentration in alveoli vs Lower in blood |
| Where does most nutrient absorption accure | Small intestines |
| Enzyme begins starch digestion | Salivary amylase |
| Main function of the large intestines | Water absorption and feces formation |
| What is peristalsis | Wave-like contractions moving food through the digestive tract |
| Smallest lymphatic vessel | Lymphatic capillaires |
| Structure that filters lymph | lypmph nodes |
| What is the function of the spleen | Filters blood, removes old RBCs, stores platlets, immune surveillance |
| What type of immunity do vaccines create | Artificail active immunity |
| Type of cells that make antibodies | B cells (plasma cells) |
| What are two major divisions of the nervous system | CNS and PNS |
| Cells that form the myelin sheeth in the PNS | Schwann cells |
| What part of the neurons recieves signals | Dendrites |
| What is a synapse | The junction between neurons where neurotransmitters are releases |
| Two main divisions of the skeleton | Axial and appendicular |
| What ion is essential for muscle contraction | Calcium |
| What are three types of muscle tissue | Skeletal, cardiac, and smooth |
| Protein filament slide to creat muscle contraction | Actin and myosin |
| Chamber that pumps oxygenated blood to the body | Left Ventricle |
| What vessel carries blood away from the heart | Arteries |
| Diastole is what | the relaction phase when the ventricles fill with blood |
| Primary function of RBC | Transport oxygen usung hemoglobin |
| Hematocrit is what | The percentage of RBC in whole blood |
| Mechanism that maintains most body functions | Negative feedbacl loop |
