Match the following terms describing electrical events with the correct phases of the cardiac cycle.
Question Selected Match
The ventricular muscle cells depolarize at the start of this phase.
During this phase, Na+ entry through the funny channels causes the pacemaker potential of SA nodal cells to gradually become less negative until it reaches threshold.
The ventricular muscle cells repolarize right before this phase.
The cytosolic concentration of calcium in the contractile cells of the ventricle is highest during this phase.
All Answer Choices
A. isovolumetric contraction
B. ventricular ejection
C. ventricular filling
D. isovolumetric relaxation

Answers

Answer:

1. Isovolumetric contraction.

2. Ventricular filling.

3. Isovolumetric relaxation.

4. Ventricular ejection.

Explanation:

In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.

Generally, the cardiac cycle occurs in two (2) stages;

Diastole : in this stage, the ventricles is relaxed and would be filled with blood.

Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.

The following terms describe the electrical events with the correct phases of the cardiac cycle in mammals (human beings);

1. Isovolumetric contraction: The ventricular muscle cells depolarize at the start of this phase. During this phase, the pressure in the atria is lower than the pressure in the ventricles while the pressure in the arteries is higher than the pressure in the ventricles.

2. Ventricular filling: During this phase, Na+ entry through the funny channels causes the pacemaker potential of SA nodal cells to gradually become less negative until it reaches threshold. It causes the atria to contract at the end of the phase.

3. Isovolumetric relaxation: The ventricular muscle cells repolarize right before this phase. During this phase, all of the four (4) cardiac valves are closed while all of the four (4) chambers are relaxed.

4. Ventricular ejection: The cytosolic concentration of calcium in the contractile cells of the ventricle is highest during this phase. Also, the atrioventricular (AV) valves are closed while the semilunar valves are open.


The difference between an open and a closed circulatory system is...

Answers

Answer:

In the closed circulatory system, blood is confined to a heart and blood vessels, whereas in an open system, hemolymph (blood) moves from a heart through vessels into interconnected spaces called a "hemocoel."

Explanation:

An open circulation the blood is not blood vessels, it instead is pumped into a cavity called Hemocoel.

A closed circulatory system, the blood is pumped through vessels SEPARATE from the interstitial fluid of the body.

QVII) Give reason for the following:
1. Light travels in a straight line​

Answers

Shadows are evidence of light travelling in straight lines. An object blocks light so that it can't reach the surface where we see the shadow. Light fills up all of the space before it hits the object, but the whole region between the object and the surface is in shadow.

Explanation:

Since the wavelength of light is very small as compared with the size of ordinary object and diffraction of light is not easily noticed and hence the light appears to travel in a straight line.

Answers

Answer:

Helens' vicitims died by asphyxiation from inhaling hot volcanic ash, and some by thermal and other injuries. The lateral blast, debris avalanche, mudflows, and flooding caused extensive damage to land and civil works. All buildings and related manmade structures in the vicinity of Spirit Lake were buried. So it would be the graph that goes down.

Explanation:

The graph that depicts the that scientists have mostly observed diversity of species in that area is graph A.

What was the impact of Mount St. Helen's eruption?

The 1980 Mount St Helens eruption in Washington state leads to the release of hot air with debris that destroyed the forests ad surrounding lands.

The victims died from inhaling the gas and others got injured. The lateral blasts and debris avalanche, along with mudflow created extensive damage to land and property.

The brain signals the body of an animal to move by transmitting electrical impulses through the neurons. An animal
is then able to walk or run because

F: the glands of the endocrine system work with the skin if the integumentary system.

G: the heart of the circulatory system works with the stomach of the digestive system.

H: the kidneys if the excretory system work with white blood cells of the immune system.

J: the muscles of the muscular system work with the bones of the skeletal system.

Answers

Answer:

J

Explanation:

The musculoskeletal system is what enables movement.

The brain signals the body of an animal to move by transmitting electrical impulses through the neurons, and the animal is then able to walk or run because the muscles of the muscular system work with the bones of the skeletal system that is present in option J.

What is the function of the neuron in muscle activity?

The neuron stimulates the muscle for the movement because the muscle has receptors for the neurotransmitters, such as at the neuromuscular junction, and the neurotransmitters either stimulate or repress the function, depending on the type of neurotransmitter.

Hence, the brain signals the body of an animal to move by transmitting electrical impulses through the neurons, and the animal is then able to walk or run because the muscles of the muscular system work with the bones of the skeletal system that is present in option J.
