What is the human body composed of?,The human body is composed of many different types of cells that together create tissues and subsequently organ systems.
What are the main components of the human body?,"The main components of the human body include the head, hair, neck, torso (which includes the thorax and abdomen), arms and hands, legs and feet."
What disciplines are involved in the study of the human body?,"The study of the human body involves anatomy, physiology, histology, and embryology."
What is homeostasis?,"Homeostasis refers to the body's ability to maintain stable internal conditions, such as safe levels of substances like sugar and oxygen in the blood."
Who studies the human body?,"The human body is studied by health professionals, physiologists, anatomists, and artists."
What are the main elements found in the human body?,"The main elements found in the human body include oxygen, carbon, hydrogen, nitrogen, calcium, phosphorus, potassium, sulfur, sodium, chlorine, and magnesium."
What is the water content in the adult male body?,"The adult male body is about 60% water, with a total water content of approximately 42 liters."
What are the main electrolytes in body water outside cells?,The main electrolytes in body water outside cells are sodium and chloride.
How many cells are there in the human body?,"At maturity, there are roughly 30-37 trillion cells in the human body."
What are the four main types of tissues in the body?,"The four main types of tissues in the body are lining cells (epithelia), connective tissue, nerve tissue, and muscle tissue."
What do lining cells regulate?,"Lining cells regulate what can and cannot pass through them, protect internal structures, and function as sensory surfaces."
What are examples of organs in the human body?,"Examples of organs in the human body include the heart, lungs, liver, gallbladder, and stomach."
What is the main function of the heart?,"The main function of the heart is to pump blood around the body, allowing for the transport of oxygen, nutrients, waste products, hormones, and white blood cells."
What are the main components of the heart?,The heart is composed of two atria and two ventricles.
What is the purpose of the atria in the heart?,The primary purpose of the atria is to allow uninterrupted venous blood flow to the heart during ventricular systole.
What is the purpose of the ventricles in the heart?,The purpose of the ventricles is to pump blood to the lungs through the right ventricle and to the rest of the body through the left ventricle.
What is the leading cause of death worldwide?,"Coronary artery disease is the leading cause of death worldwide, making up 16% of all deaths."
What is the function of the gallbladder?,The gallbladder stores bile before it is released into the small intestine to help with the digestion of fats.
What is a common disease of the gallbladder?,Gallstones is a common disease in which one or more stones form in the gallbladder or biliary tract.
What are the main systems of the human body?,"The main systems of the human body include the circulatory system, digestive system, endocrine system, immune system, integumentary system, lymphatic system, musculoskeletal system, nervous system, and reproductive system."
What is the function of the circulatory system?,"The circulatory system propels the circulation of the blood, which serves as a 'transportation system' to transfer oxygen, fuel, nutrients, waste products, immune cells, and signaling molecules from one part of the body to another."
What is the function of the digestive system?,"The digestive system converts food into small, nutritional, non-toxic molecules for distribution and absorption into the body."
What is the function of the endocrine system?,The endocrine system produces and releases hormones that regulate various bodily functions and processes.
What is the function of the immune system?,The immune system provides a mechanism for the body to distinguish its own cells and tissues from outside cells and substances and to neutralize or destroy the latter.
What is the function of the integumentary system?,"The integumentary system consists of the skin and its appendages, providing containment, structure, and protection for other organs, and serving as a major sensory interface with the outside world."
What is the function of the musculoskeletal system?,The musculoskeletal system gives the body basic structure and the ability for movement.
What is the function of the nervous system?,"The nervous system is responsible for coordinating and controlling bodily functions, including thought, memory, sensory processing, and movement."
What is the function of the reproductive system?,The reproductive system is responsible for producing new humans and ensuring their sexual development for reproduction.
