In Myeloid hemopoiesis we can produce all formed elements.
True
In red bone marrow
An erythrocyte CFU can differentiate into other formed elements?
False.
It can now only produce RBC
We secrete hormones from the adenohypophysis
True
We secrete hormones in the neurohypophysis
False
- We only release hormones made in the hypothalamus
Prolactin is involved in releasing milk
False
OT releases milk
OT is involved in making milk
False
Prolactin makes milk
Hemostasis is maintaining an internal balance
False
Hemostasis is the process that stops bleeding
Platelet’s primary function is blood clotting
True
Pulmonary arteries transport oxygen-rich blood away from the heart
False
The heart receives blood when the heart contracts
False
It receives blood when its relaxed from the openings in the semilunar valves.
Cardiocytes have contractile proteins that are arranged exactly like skeletal muscle cells
True
The central nervous system tells the heart to contract
False
The cardiac conduction system does
The central nervous system tells the heart to speed up or slow down.
True
The autonomic nervous system will innervate the heart and control the rate of the contractions
True
Sympathetic will increase it by influencing the SA node, AV node, and cardiac muscle
Parasympathetic slows it down with the SA and AV node.
Before the cardiac conduction system fires the heart is completely at rest
True
The ventricles should produce the same stroke volume
True
or edema could develop in lungs or tissues
Tunica media can be involved in regulating blood flow through arteries
True
By using vasomotion (can contract or relax)
The vasovasorum is found in the tunica interna of blood vessels
False
Found in Tunica externa
All of the capillary beds in the body are open at all times
False
Pressure would drop
The heart pumps blood into veins
False
Arteries lead to capillaries
True
All capillaries are functional at the same point in time
False
Veins have little to no pressure but have continued flow towards the heart.
True
Viscosity is something we keep at homeostasis
True
It’s set at a certain level, we regulate it.
Lymphatic tissue is a new tissue recently discovered
False
its a collection of lymphatic cells within one of the other tissue types.
The thoracic duct starts below the diaphragm
True
starts as cisterna chili
Lymphatic capillaries are blind-ended capillaries that start around our blood capillaries
True
a difference in lymphatic capillaries have large gaps between endothelial cells
For immune clearance to occur you need an antibody
True
In cellular immunity, T-cells will actively destroy pathogens
True
B-cells are part of humoral immunity, they wander around the lymphatic system actively seeking and destroying pathogens
False
The antigen is the smaller part of the epitome
False
The epitome is the smallest part of the antigen. The epitome is what we respond to.
B-cells can function as APCs
True
T helper cell is the most important immune cells because it plays a role in specific and non-specific defenses
True
B-cells are responsible for making antibodies as part of humoral immunity
False
Plasma cells are responsible for making antibodies as part of humoral immunity
True
The entire respiratory system is involved with gas exchange
False
A lot of it is just moving air
Epiglottis, thyroid, and cricoid are composed of hyaline cartilage
False
Epiglottis is elastic cartilage
In gas exchange, the gas only crosses one cellular membrane
False
E-neurons physically make muscles contract in order for you to expire
False
The VRG can be influenced by both the DRG and PRG to change respiratory cycle
True
When we inspire the pressure on the external environment is greater than the pressure in the lungs.
True
O2 and CO2 are soluble in water
True
For systemic gas exchange to happen oxygen unloads first
False
For alveolar gas exchange CO2 comes out first
False
O2 has to go in first
Juxtamedullary nephrons are used to make normal dilute urine
False
They make concentrated urine
In DCT we have urine
False
there we have filtrate
The paratenium is similar to the pericardial sac and the pleura in thoracic cavity
True
The lower esophageal sphincter is a true sphincter
False
The gastric pits produce the gastric juice
True
HCl and digestive enzymes
The parietal cells make HCl acid via the use of CAH
True
We use ATP in production of HCl acid
True
The taenia coli is the longitudinal layer of the muscularis externa
True
Pepsinogen digests protein
False
Pepsinogen is an inactive enzyme, it has to be pepsin
If the chemiosmotic mechanism is not working we can still make ATP within the mitochondria
False
Oxygen has to be present to go into pyruvic decarboxylation
True
if not present we go into anaerobic fermentation (lactid acid)
In order to make ATP in the electron transport chain we rely on chemiosmotic mechanism
True
Glycogenesis is the breakdown of glycogen into glucose
False
that would be glycogenolysis
When we break down lipids the products of lipolysis end up getting plugged into carbohydrate metabolic pathway
True
In order for the mesonephric ducts to develop nothing else has to be added or expressed
False
SRY gene has to be expressed
The countercurrent heat exchanger is going to cool the blood on his way down tot he testes
True
Once the cells are in the cells are in the ____ canal they are protected from immune system
True
The urogenital system can be used to describe the female reproductive system
False
It can be used for the male system.
