Answer:
- glomerular filtration rate homeostasis and glomerular hydrostatic pressure homeostasis
Explanation:
Glomerulus receives blood from Afferent arteriole and blood is take away from glomerulus by efferent arteriole. Glomerulus or glomerular capillaries are similar to blood capillaries but are more permeable due to fenestration or pores. The mechanism of urine formation involves three steps of which the first step is glomerular filteration or ultrafilteration. Glomerular flteration depends upon 3 main pressures:
a. glomerular blood hydrostatic pressure (GBHP).
b. capsular hydrostatic pressure
c. blood colloidal osmotic pressure
GBHP is the natural arterial pressure, occurs due to wider diameter of afferent compared to efferent arteriole. GBHP is around 60 mm of Hg. Altering the radii of afferent or efferent arteriole would alter the the glomerular filtration rate by changing the glomerular hydrostatic pressure.
Answer:
the temperature of planets closes to the sun is hotter than planets far away
Dorsal Body Cavity: Cranial cavity, enclosed by the skull and contains the brain. Spinal canal, enclosed by the spine and contains the spinal cord.
Ventral Body Cavity: Thoracic cavity, enclosed by the rib-cage and contains the lungs and heart.
Abdominal cavity/Pelvic cavity, contains the digestive organs, spleen kidneys, bladder, and reproductive organs.
Complete Question: In apneustic breathing, which is practiced by most marine mammals:
A. A small amount of air is kept in the lungs before diving
B. A large amount of air is kept in the mouth before diving
C. Normal breathing is maintained before diving
D. Several deep breaths are taken before exhaling and diving
E. No actual breathing takes place before diving
Answer: D. Several deep breaths are taken before exhaling and diving.
Explanation:
Common dolphins, whales and other marine mammals are known to undergo apneustic breathing. This breathing process is characterized by periodic or several breathe inhalation, followed by holding their breath and then exhaling them.
Marine mammals can afterwards, went on to dive. This process prevent high water loss out. Thus, they make fewer respirations while maximizing the amount of oxygen produced for optimal consumption.
The prey would increase in numbers, since their predator is now extinct.
