Circulation And The Skeletal Systems

2.

The _________ are the junction between the arteries and the veins

Explanation
Capillaries are the smallest blood vessels in the body and serve as the junction between arteries and veins. They connect the arterial system to the venous system, allowing for the exchange of oxygen, nutrients, and waste products between the blood and surrounding tissues. Capillaries have thin walls that facilitate the diffusion of substances, making them ideal for this exchange process. Overall, capillaries play a crucial role in maintaining proper blood flow and delivering essential substances throughout the body.

The two types of circulation are:

Systolic and Diastolic
Pulmonary and Systolic
Systemic and Pulmonary
Systemic and Diastolic

Correct Answer

A. Systemic and Pulmonary

Explanation

The correct answer is Systemic and Pulmonary. Systemic circulation refers to the circulation of blood throughout the body, delivering oxygen and nutrients to the tissues and organs. Pulmonary circulation, on the other hand, is the circulation of blood between the heart and the lungs, where oxygen is picked up and carbon dioxide is released. These two types of circulation work together to maintain the overall functioning of the cardiovascular system.

What is the name of the large bone that sits above the knee cap?

Patella
Tibia
Fibula
Femur
Humerus

Correct Answer

A. Femur

Explanation

The femur is the large bone that sits above the knee cap. It is the longest and strongest bone in the human body, extending from the hip to the knee. The patella, on the other hand, is the small bone commonly known as the knee cap that sits in front of the knee joint. The tibia and fibula are the two bones in the lower leg, while the humerus is the bone in the upper arm.

What is not one of the four parts that make up blood?

White Blood Cells
Red Blood Cells
Platelets
Lymph
Plasma

Correct Answer

A. Lymph

Explanation

Lymph is not one of the four parts that make up blood. Blood is composed of red blood cells, white blood cells, platelets, and plasma. Lymph, on the other hand, is a clear fluid that is part of the lymphatic system and helps in immune function. While lymph is closely related to blood, it is not considered one of the components that make up blood itself.

What is the name of the oxygen carrying molecule found in these structures?

Hemocyanin
Phagocytes
Hemoglobin
Heme

Correct Answer

A. Hemoglobin

Explanation

Hemoglobin is the correct answer because it is the oxygen carrying molecule found in the given structures. Hemoglobin is a protein found in red blood cells that binds to oxygen in the lungs and carries it to the body's tissues. It plays a crucial role in transporting oxygen throughout the body and is essential for proper functioning of the cells and organs. Phagocytes are a type of white blood cell involved in immune response, hemocyanin is an oxygen-carrying protein found in some invertebrates, and heme is a component of hemoglobin.

7.

What molecule binds the oxygen to the hemoglobin?

Calcium
Iron
Magnesium
Carbon

Correct Answer

A. Iron

Explanation

Iron is the correct answer because it is the molecule that binds the oxygen to the hemoglobin. Hemoglobin is a protein found in red blood cells that carries oxygen from the lungs to the rest of the body. The iron molecule within the hemoglobin binds to the oxygen molecules, allowing for transportation and delivery of oxygen throughout the body.

Choose the correct statement from the statements below:

Humans have an open circulatory system, where as most invertebrates have a closed circulatory system
Humans have a closed circulatory system, where as most invertebrates have an open circulatory system

Correct Answer

A. Humans have a closed circulatory system, where as most invertebrates have an open circulatory system

Explanation

The correct answer is that humans have a closed circulatory system, whereas most invertebrates have an open circulatory system. In a closed circulatory system, blood is contained within vessels and pumped by a heart, allowing for more efficient transport of oxygen and nutrients. In contrast, in an open circulatory system, blood is not contained within vessels and flows directly through body cavities, limiting the efficiency of oxygen and nutrient delivery. This distinction is a fundamental difference between the circulatory systems of humans and most invertebrates.

How many chambers does a human heart have?

20
8
3
4
5

Correct Answer

A. 4

Explanation

A human heart has four chambers. The heart is divided into two sides - the left side and the right side. Each side has two chambers, an upper chamber called the atrium and a lower chamber called the ventricle. The left side of the heart receives oxygen-rich blood from the lungs and pumps it to the rest of the body, while the right side receives oxygen-poor blood from the body and pumps it to the lungs to be oxygenated. Therefore, the correct answer is 4.

10.

Which chambers in the heart are responsible for pumping blood?

Atria
Ventricles
Arteries
Veins

Correct Answer

A. Ventricles

Explanation

The ventricles are responsible for pumping blood in the heart. They are the lower chambers of the heart and have thicker walls compared to the atria. When the ventricles contract, they push blood out of the heart and into the arteries, which then carry the oxygen-rich blood to the rest of the body. The atria, on the other hand, receive blood returning to the heart and help to fill the ventricles before they pump again. Arteries and veins are blood vessels that carry blood throughout the body and are not responsible for pumping blood.
