| Question | Answer |
|---|---|
| What happens if venous capillaries absorb too much fluid? | Less fluid becomes lymph, which can affect the body’s ability to remove waste and support the immune system. Fact: Poor lymph flow can lead to lymphedema—swelling caused by fluid buildup in tissues. |
| How is lymph formed in the body? | Lymph forms when interstitial fluid from leaking capillaries enters lymphatic vessels. Fact: Lymph not only removes waste but also transports white blood cells that fight infection. |
| Why is the term “circulation” not ideal for describing lymph flow? | Lymph moves in one direction toward the heart and depends on valves, muscle movement, and breathing. Fact: Unlike blood, lymph doesn’t have a pump like the heart to push it through the body. |
| What does the adrenal gland produce and where is it located? | It produces adrenaline, cortisol, and aldosterone and is located on top of each kidney. Fact: Cortisol is known as the “stress hormone” because it helps regulate metabolism and the stress response. |
| What do the parathyroid glands regulate in the body? | They maintain calcium balance through parathyroid hormone (PTH). Fact: These glands are tiny—about the size of a grain of rice—but critical for bone and nerve health. |
| What hormone is produced by the pineal gland, and what is its function? | Melatonin, which regulates the sleep-wake cycle. Fact: Melatonin production is influenced by light—levels rise in the dark and fall in bright light. |
| Which hormones are released by the posterior pituitary gland? | Oxytocin and antidiuretic hormone (ADH). Fact: Oxytocin plays a major role in childbirth and bonding, while ADH helps the body retain water. |
| What is the role of the anterior lobe of the pituitary gland? | It produces hormones like GH (growth hormone) and TSH (thyroid-stimulating hormone). Fact: The anterior pituitary is often referred to as the “master gland” because of its role in regulating many other endocrine glands. |
| How does Parkinson’s disease affect the nervous and muscular systems? | It causes issues with movement, balance, and coordination, leading to tremors, stiffness, and injuries. Fact: Parkinson’s can also cause speech difficulties and affect digestion, leading to constipation. |
| What is the main cause of Parkinson’s disease? | Parkinson’s is caused by the loss of dopamine-producing nerve cells in the substantia nigra of the midbrain. Fact: As the disease progresses, it can also affect the frontal lobe, leading to memory and thinking problems. |
