Test specific questions Flashcards
Name the four chambers of the heart
- Two upper atriums
- Two lower ventricles
Why are the pulmonary arteries and pulmonary veins named differently?
They carry different types of blood.
Your pulmonary arteries carry oxygen-poor blood. Your pulmonary veins carry oxygen-rich blood. They basically do the inverse of what their blood vessel type is supposed to do.
How does the diaphragm work?
The diaphragm contracts and flattens and the chest cavity enlarges. This contraction creates a vacuum, which pulls air into the lungs. Upon exhalation, the diaphragm relaxes and returns to its domelike shape, and air is forced out of the lungs.
Why does the diaphragm work the way it does?
- Increase space in the chest cavity
- Allow inhalation to occur
- Allow for more air to be breathed in
What would happen to a person’s body if the diaphragm failed to work?
- They would have reduced
breathing capabilities - They would possibly be unable
to control their voluntary
breathing - They would have inadequate
and inefficient gas exchange - In the worst instance, you will
suffocate.
What would happen if your heart stopped working? (Step - by - Step)
It will lead to a lack of oxygen-rich blood which will result in death. Blood stops flowing to your organs and your cells become deprived of oxygen and nutrients. Due to that, your bodies various systems can no longer work without a constant blood supply.
Name all of the components of the circulatory system as if you were the oxygen molecule.
Nose or nasal cavity
Pharynx
Larynx
Trachea
Bronchi (Bronchus)
Bronchioles
Alveoli
Describe the relationship between the respiratory and circulatory system
The circulatory system, which is made up of the heart and blood vessels, supports the respiratory system by bringing blood to and from the lungs. The circulatory system helps deliver nutrients and oxygen from the lungs to tissues and organs throughout the body. It also helps remove carbon dioxide and waste products. The respiratory system brings in the required oxygen molecules to the bloodstream and takes out carbon dioxide
List all of the components of the male reproductive system
- Epididymis
- Testes
- Penis
- Urethra
- Vas deferens
- Seminal Vesicle
- Bladder
- Prostate Glands
List all of the components of the female reproductive system
- Urethra
- Fallopian Tube
- Ovaries
- Uterus Lining
- Cervix
- Vagina
Why is menstruation painful for women?
A hormone called prostaglandin triggers muscle contractions in your uterus that expel the lining. These contractions can cause pain and inflammation
When do estrogen levels increase during the menstrual cycle?
When ovulation occurs.
Why does progesterone increase during a menstrual cycle?
It maintains the endometrium (uterus lining) and prepares for a fertilized egg to implant itself and grow. If this doesn’t happen, the lining breaks down and progesterone levels drop.
Give and explain 2 methods of preventing pregnancy
- Abstinence = One does not engage in sexual intercourse and therefore means that one cannot fall pregnant as there is no opportunity for copulation and fertilization to occur.
- Oral contraceptive pill = The pill prevents the ovaries from releasing an egg each month (ovulation). It also: thickens the mucus in the neck of the womb, so it’s harder for sperm to reach an egg. thins the lining of the womb, so there’s less chance of a fertilized egg implanting into the womb and being able to grow
Explain why a pregnant woman gets hungrier and suffers from fatigue faster than a non-pregnant woman.
- A certain portion of the food consumed goes directly to the baby
- The mother’s body consumes more energy and calories because it has to sustain the needs of two organisms.
- Increased progesterone levels make you sleepy.
