Which system controls the activities of the body?
Central nervous system . The central nervous system definition is that it receives information from the body’s environment and generates instructions, thereby controlling all the activities of the human body. This two-way information flow into, and out of, the CNS is conveyed by the peripheral nervous system.
What is the digestive system?
Digestive system - anterior view. The human body is a biological machine made of body systems; groups of organs that work together to produce and sustain life. Sometimes we get lost while studying about cells and molecules and can’t see the forest for the trees.
What is the circulatory system?
They all comprise a continuous network of vessels which act to carry blood around the body. Blood leaves the heart via arteries, these progressively reduce in size to continue as smaller arterial vessels called arterioles. Arterioles end in a web of even smaller vessels called capillaries. The exchange of gases and nutrients occurs through the capillary walls.
What is the cardiovascular system?
The cardiovascular system is comprised of the heart and the circulatory system of blood vessels. The heart is composed of four chambers; two atria and two ventricles. Blood enters the heart through the upper chambers of the left and right atria and exits via the left and right ventricles.
How many circuits are there in the circulatory system?
There are three separate circuits to the circulatory system.
What are the respiratory organs?
The respiratory system consists of a series of organs; the nasal cavity, pharynx, larynx, trachea, bronchi, bronchioles and lungs ( alveoli ). The nasal cavity and pharynx are together called the upper respiratory system, while the remainder of the organs comprise the lower respiratory system.
Why is skin important to the body?
Skin is our body’s first line of defense against pathogens, harmful substances, injuries, and more. It also controls how much heat and water our body loses to the environment, allowing us to sweat. Even goosebumps are part of our skin’s regulation system; the tightening of the skin raises our fine hairs upright, trapping warm air close to our skin.
What are the functions of the endocrine system?
The endocrine system allows the body to respond to environmental changes, and to other types of survival changes, such as the need to reproduce. Some examples of messages sent by the endocrine system are: 1 Fight or flight response – When a threat appears in the environment, the adrenal glands secrete a flood of adrenaline. In response to this chemical message, the heart pumps blood faster, breathing deepens to take in more oxygen, and the nervous system sharpens perception and memory formation. Other changes also occur to make the body ready to fight or flee from a potential threat. 2 Reproductive signals – When the body is ready to reproduce, the ovaries or testes send chemical messages that influence other organs, including the brain. In the female reproductive system, preparing the uterus for pregnancy involves a complex cascade of chemical messages that repeat on a monthly cycle – the menstrual cycle. 3 Hungry or full – When the body is hungry, your stomach releases a hormone (called ghrelin) that tells the brain and other organ systems to start seeking food. When the body is full, on the other hand, another set of hormone messengers (including a hormone called leptin) are released to tell your body to stop eating.
How does the liver help the body digest food?
The liver helps the process of digestion by releasing substances that assist the stomach and intestines in breaking down food, and by breaking down toxic substances in the blood. Once the nutrients have been extracted from foods, they are distributed to the body’s cells by the circulatory system.
Why do cells die in a heart attack?
Without oxygen to fuel cellular respiration, cells begin to die within minutes. This is the primary reason that heart attacks are deadly. Although the heart is part of the circulatory system, not the respiratory system, it is responsible for transporting oxygen from the lungs to our cells.
What is the endocrine system?
The endocrine system consists of a number of tissues that send out chemical messages – called ‘hormones’ – to the rest of the body. Each of these messages has its own unique purpose, to which the body’s other systems respond accordingly.
How long does it take for blood to circulate?
The body’s entire blood volume takes about a minute to circulate – making this a truly high-speed expressway for distributing oxygen, nutrients, messages, and removing waste. The heart is the central pump of the circulatory system, sending blood throughout the body at very high speeds.
What are the components of the cardiovascular system?
These substances include oxygen, nutrients, hormones, and waste products. The cardiovascular system includes the heart, the blood, and the blood vessels. The cardiovascular system is a highly efficient system for moving substances around the body.
What is the function of the body?
Body Functions. Body functions are the physiological or psychological functions of body systems. The body's functions are ultimately its cells' functions. Survival is the body's most important business. Survival depends on the body's maintaining or restoring homeostasis, a state of relative constancy, of its internal environment.

How many systems are there in the human body?
The body is made up of 11 systems that work together.
Which system is responsible for transporting oxygen-rich blood to all of the body's organs and tissues?
The cardiovascular system with its heart-pump and network of arteries and veins shuttles oxygen-rich blood from the lungs to all of the body's organs and tissues. Cells throughout the body take their fill of oxygen and nutrients and dispose of carbon dioxide and waste products, which eventually flow back to the heart's right-sided chambers; then on to the lungs to exchange carbon dioxide with oxygen. Inhaled air passes through your nasal passages, throat and lung airways reaching tiny alveoli, the site of gas exchange. The newly oxygen-rich blood travels back from the lungs to the heart's left-sided chambers, where it gets pumped out at great pressure via arteries to reach the needy tissues once again. And so the cycle continues. Other organ systems, such as the endocrine and nervous system, directly and indirectly regulate the cardiovascular system.
What is the endocrine system?
The endocrine system largely governs many processes related to reproduction and sexual maturity, as well. Advertisement.
