“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”

What type of structure in nerve cells must grow in order for sensory information to be relayed to the spinal cord?
larisa86 [58]

For sensory information to be relayed the nerve cells should have an axon.

<u>Explanation</u>:

  • Nerve cells or neurons play a critical role in transmitting signals from various sense organs of the body to the spinal cord where it is processed.
  • Neurons have different parts - the dendrites which are tiny branches that receive incoming signals from the body, the nucleus, and the axon.
  • The axon is a long fiber that is covered by a protective layer called myelin sheath. It is this structure of the nerve cell or neuron that helps transmit signals to the Central Nervous System of which the spinal cord is a part.

natali 33 [55]

Answer: a. A conscious being is dissected.

Explanation:

A vivisection is an experimental process in which the living being is dissected. It is typically done on organisms that are conscious and they have a central nervous system. This is mainly done for experimentation and research but all human surgeries are examples of vivisections. This is done to observe the internal structure of the organism.

erik [133]

The correct response is Feet and ankles.

<h3>What is the term for the ankles?</h3>

The region where the foot and the leg converge is known as the ankle, the talocrural region, or the jumping bone (informally). Three joints make up the ankle the subtalar joint, the inferior tibiofibular joint, and the ankle joint proper, also known as the talocrural joint.

<h3>Where is the ankle bone located?</h3>

The tibia, the larger and stronger of the two lower leg bones, makes up the inside of the ankle and is part of the real ankle joint, which is made up of three bones the outside portion of the ankle is made up of the fibula, a tiny bone in the lower leg.
