“The Cardiovascular System: Cardiac Cycle
1.
Valves open in response to _________________ on their two sides.
Blood pressure
2.
List the chambers/ vessels that the four valves connect:
______(1)______ Pulmonary semilunar ______(2)_____
______(3)______ Aortic semilunar ______(4)_____
______(5)______ Mitral ______(6)_____
______(7)______ Tricuspid ______(8)_____
1. R. ventricle
2. Pulmonary artery
3. L. ventricle
4. Aorta
5. L. atrium
6. Pulmonary vein
7. R. atrium
8. Inferior/superior vena cava
3.
a. Ventricular filling occurs during______ ventricular_________.
b. Blood flows through the _______ or __________ valves into the ventricles.
1. Mid-late
2. Diastole
3. Mitral
4. Tricuspid
4.
During Ventricular systole, what closes the AV valves?
Intraventricular pressure rising and causing ventricular contractions.
5.
During ventricular systole, what opens the semilunar valves?
Ventricles contract, raising pressure, bblood pressure then forces the semilunar valves open.
6.
During Isovolumetric relaxation, what closes the semilunar valves?
When blood pressure in the artery exceeds the blood pressure in the ventricle.
7.
During Isovolumetric relaxation, what opens the AV valves?
When blood pressure in the ventricle exceeds the blood pressure in the arteries.
8.
Why is hypertension hard on the heart?
Beacuse overtime high blood pressure causes heart muscles to thicken, which means more work to pump blood through vessels. It can cause heart disease because of heart constantly overworking.
9.
Looking at the ventricular volume graph, the stroke volume is approximately how many ml?
70ml
10.
During the four phases listed below, state whether the AV and semilunar valves are opened or closed:
1. Ventricular Filling
2. Isovolumetric
3. Ventricular Ejection
4. Isovolumetric
1. AV: Opened, Semilunar: Closed
2. AV: Closed, Semilunar: Closed
3. AV: Closed, Semilunar: Opened
4. AV: Closed, Semilunar: Closed”
Answer:
B) inferior epigastric
Explanation:
Inferior epigastric
It is present in the fat of the preperitoneal . It lies superficially to peritoneum and make the lateral umbilical fold .
Hernias can pass medial or lateral to these vessels .
<u>In case the Hernia and vessels both are lateral , then it is the indirect inguinal hernia .</u>
<u>And , if the hernia and the vessels are medial , then it is the direct inguinal hernia .</u>
first off it depends what your goal is lets just guess its to be have 100mil followers. First behaviors no one likes a salty person also you can act all sly that is popular with people like corpse husband. Second follow the trends even if your goal is just to be a rich person not have followers follow the trends people are investing in dogecoin maybe invest in that to. Its important to make these changes right away cause dogecoin is probably gonna go down.
Answer:
Autism impacts many systems in the body, including the metabolic, mitochondrial, immunological, gastrointestinal and the neurological. These systems interact in complex and highly interdependent ways. New research is challenging the long-held belief that autism affects only those regions of the brain that control social interaction, communication, and reasoning -- suggesting, instead, that the disorder affects the entire brain.
