Questions and Answers

Match the following components of blood with their functions:

Red Blood Cells (RBCs) = Carry oxygen and carbon dioxide White Blood Cells (WBCs) = Fight against germs and produce antibodies Platelets = Help in blood clotting

Which one of the following organs is NOT a part of the respiratory system?

Alveoli

Trachea

Lungs

Liver (correct)

What is the main function of the diaphragm?

The diaphragm is a dome-shaped muscle that contracts and relaxes to help with breathing. During inhalation, it contracts and flattens, expanding the chest cavity. During exhalation, it relaxes and moves upwards, decreasing the chest cavity.

What is the difference between external respiration and internal respiration?

External respiration is the exchange of gases between the body and the environment, while internal respiration is the exchange of gases between the blood and the cells. Signup and view all the answers

Why is blood donation considered superior to other donations?

What is the function of the alveoli in the lungs?

The alveoli are tiny air sacs in the lungs where the exchange of oxygen and carbon dioxide takes place between the blood and the air we breathe. Signup and view all the answers

Explain how the respiratory, digestive, and circulatory systems work together.

The digestive system breaks down food into nutrients, which are absorbed into the bloodstream by the circulatory system. The circulatory system then transports these nutrients to cells throughout the body. The respiratory system provides oxygen to the blood, which is carried to the cells by the circulatory system, and removes carbon dioxide from the cells, transporting it to the lungs to be exhaled.

What are some health parameters that should be checked before donating blood?

A blood donor should be healthy, have a normal hemoglobin level, and not have any infectious diseases or addictions. They should also be eligible based on their blood type and other factors. Signup and view all the answers

What is the difference between arteries and veins?

Arteries carry oxygenated blood away from the heart to the body's tissues, while veins carry deoxygenated blood back to the heart. Arteries are thicker and have higher blood pressure than veins. Signup and view all the answers

What is the main cause of high blood pressure?

High blood pressure, or hypertension, can have various causes, including lifestyle factors like obesity, lack of exercise, high sodium intake, and stress, as well as underlying medical conditions. Signup and view all the answers

What are some steps that someone with hypertension can take to manage their condition?

People with hypertension should consult a doctor to determine the best treatment plan for their specific situation. It may involve lifestyle changes such as losing weight, exercising regularly, reducing salt intake, and managing stress. Medications may also be prescribed. Signup and view all the answers

Study Notes

Human Body and Organ Systems - Study Notes

Heartbeats: Group A - 72 per minute, Group B - 72 per minute
Red Blood Cells (RBCs): Group A - 50-60 lakh/mm³, Group B - 5000-6000 per mm³
White Blood Cells (WBCs): Group A - 5000 - 6000 per mm³, Group B - 5000-6000 per mm³
Blood Donation Value: Blood donation is considered superior because it cannot be manufactured and can save a human life.
Normal Body Temperature: 37°C
pH of Oxygenated Blood: 7.4

Respiratory System

Organs: Nose, Pharynx (throat), Windpipe (trachea), Lungs, Alveoli, Diaphragm
Functions: Inhaling and exhaling air; filtering, warming, and humidifying air; a common passage for food and air; carries air to the lungs; space for gas exchange; actual gas exchange; controlling breathing movements
Respiratory System and Circulatory System: these systems work in coordination for oxygen uptake and carbon dioxide release.

Circulatory System

Organs: Heart, Arteries, Veins, Blood Capillaries, Blood
Functions: Muscular pump; carry blood away from heart; carry blood to the heart; exchange of oxygen, nutrients, hormones, vitamins, etc.; various functions depending on blood cell type (RBCs carry oxygen/carbon dioxide, WBCs fight disease, platelets clot blood); carries out definite functions and gives fluidity to blood.

Blood and Blood Groups

Human Blood Color: Red due to hemoglobin, a protein with iron.
Diaphragm Movement: Up and down consecutively during breathing; This creates pressure changes for air intake and exhalation
Universal Donor: Blood type O is considered as a universal donor because it does not have antigens that cause clotting reactions in recipients

Health Parameters for Blood Donors

Donors: Should be healthy with normal RBC and WBC counts; should not have HIV, infectious diseases or be under the effects of substances like drugs or alcohol

Internal Structure of Heart

Diagram showing: right and left pulmonary arteries, superior/inferior vena cava, right/left atrium, bicuspid/tricuspid valves, left ventricle, semilunar valve of systemic aorta, etc.

Functional Correlation of Systems

Circulatory, Respiratory, Digestive, and Excretory Systems: Respiratory system provides oxygen to the circulatory system, the digestive system provides nutrients, and the excretory system removes waste. They work together to keep the body functioning.
