• Neurons are specialized cells that transmit electrical impulses to other neurons or muscles.
• Photosynthesis the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.
• The nervous system is responsible for receiving, processing, integrating, storing, retrieving, interpreting, and responding to information from both within and outside the body
• The endocrine system consists of glands that secrete hormones directly into the bloodstream, where they travel to target organs or tissues throughout the body.
• Hormones are chemical messengers produced by various glands in the body that regulate metabolism, growth and development, tissue function, sexual function, sleep, and mood, among other things.
• chlorophyll is a green pigment to make present in all green plants and in cyanobacteria, which is responsible for the absorption of light to provide energy for photosynthesis.
• Gas Exchange occurs when oxygen diffuses from the alveoli into the capillaries surrounding them, while carbon dioxide moves in the opposite direction.
• Breathing is the act of taking in oxygen and expelling carbon dioxide through the mouth and nostrils.
• the respiratory system is made up of structures such as the nose, trachea (windpipe), bronchi, lungs, diaphragm, and chest wall, which work together to facilitate breathing and gas exchange between the air and the blood.
• the respiratory system is made up of structures such as the nose, trachea (windpipe), bronchi, lungs, diaphragm, and chest wall.
• The heart pumps blood around the body via arteries, veins, and capillaries.
• The respiratory system plays a crucial role in maintaining homeostasis by providing oxygen to cells throughout the body and removing waste products like carbon dioxide.
• Capillaries are tiny vessels that connect arteries and veins
• The respiratory system includes the nasal cavity, pharynx, larynx, trachea, bronchi, lungs, and pleural cavities.

• Capillaries are tiny vessels that connect arteries and veins
• The respiratory system consists of organs and tissues involved in the process of breathing and gas exchange with the environment.
• The respiratory system consists of organs and tissues involved in the process of breathing and gas exchange with the environment.
• During exhalation, air flows out of the lungs due to the decrease in pressure inside the chest cavity compared to atmospheric pressure.
• During exhalation, air flows out of the lungs due to the decrease in pressure inside the chest cavity compared to atmospheric pressure.
• The circulatory system transports nutrients, oxygen, hormones, and waste products around the body through the heart, arteries, veins, and capillaries.
• The circulatory system transports nutrients, oxygen, hormones, and waste products around the body through the heart, arteries, veins, and capillaries.
• Veins return blood back to the heart
• Veins return blood back to the heart
• Exhalation (breathing out) involves the relaxation of the diaphragm muscle, allowing it to return to its original position and decreasing the volume of the thoracic cavity.
• Exhalation (breathing out) involves the relaxation of the diaphragm muscle, allowing it to return to its original position and decreasing the volume of the thoracic cavity.
• The digestive system breaks down food into smaller molecules so it can be absorbed into the bloodstream and used by cells for energy, growth, and repair.
• Arteries carry blood away from the heart
• Inhalation (breathing in) involves the contraction of the diaphragm muscle, causing it to move downward and increasing the volume of the thoracic cavity.
• Blood carries nutrients, hormones, and other substances that are essential for cellular function.
• Arteries carry blood away from the heart under high pressure.
• Veins carry oxygenated blood back to the heart
• Arteries carry oxygenated blood away from the heart towards organs and tissues.
• The respiratory system is responsible for breathing, which involves taking in air through the nose or mouth and exhaling it out through the mouth or nose.
• Veins return blood back to the heart at lower pressures.
• The respiratory system is responsible for supplying oxygen to the body's cells and removing carbon dioxide from them.
• Veins return deoxygenated blood back to the heart.
• The respiratory system is responsible for exchanging gases between the body's internal environment and external environment through the process of ventilation (breathing).
• Blood pressure refers to the force exerted on the walls of blood vessels due to the flow of blood.
• Capillaries allow for the diffusion of gases and nutrients into and out of cells.
