Explanation:
Answer: See explanation
Explanation:
• Stability: this is defined as the ability of a certain body to go back to its original position or equilibrium when such body is displaced.
• Maximum Effort: This is the use of maximum force towards accomplishing a particular objective e.g lifting of weight.
• Maximum Velocity: Thus is the maximum speed that a certain body uses to move in a particular direction. We should note that when there's maximum speed, there's acceleration is zero.
• Impluse: It is the effect of a force that acts over time.
• Reaction:
• Torque: It is the rate of change that occurs in the angular momentum of a certain object.
• Angular Momentum: It measures the rotational momentum that occurs in a system.
Answer:
1. The blood entering the right side of the body contains <u>un-
oxygenated</u> blood (B).
2. All arteries carry oxygenated blood EXCEPT the <u>pulmonary</u> artery.
3. What structure brings blood to the right atrium? Superior and inferior vena cava (D).
Explanation:
The cardiovascular system is responsible for getting blood to organs throughout the body, through the joint function of the heart and blood vessels.
The circulation of the blood has been divided into two circuits:
- The major circulation, which includes the exit of blood from the heart to the arterial system, to go to the whole body. This circuit is closed with the arrival of blood to the heart through the system of venous vessels.
- The minor circulation consists of the passage of blood from the right ventricle to the lungs, and from these to the left atrium.
The blood that reaches the right atrium —entering to right side— proceeds from the superior and inferior vena cava, and is non-oxygenated blood.
In the minor circulation, the pulmonary arteries exit the right ventricle, carrying non-oxygenated blood to the lungs, being the <u>only arteries to carry venous blood</u>.
White blood cells are part of the immune system. They usually fight infections and attacks viruses and bacteria. A white blood cell count measures the number of white blood cells in one's body. This helps to check of an inflammatory disorders or other diseases. There are 4x109 and 11x109 white blood cells in 1 liter of healthy adult blood that is about 7000 to 25000 WBC per drop out of the 37.2 trillion cells in the body.
