What will happen to the organism if tissues are injured?
Upon tissue injury, damaged cells release inflammatory chemical signals that evoke local vasodilation, the widening of the blood vessels. Increased blood flow results in apparent redness and heat. In response to injury, mast cells present in tissue degranulate, releasing the potent vasodilator histamine.
How does tissue organs and organ systems help to keep organisms alive?
They work together to circulate the blood, bringing oxygen and nutrients to cells throughout the body and carrying away carbon dioxide and metabolic wastes. Another example is the respiratory system, which brings oxygen into the body and gets rid of carbon dioxide.
In what ways are the functions of the organ systems of plants similar to those animals?
Plant Organ Systems In plants, just as in animals, similar cells working together form a tissue. When different types of tissues work together to perform a unique function, they form an organ; organs working together form organ systems.
Why can you not function properly without one of your body systems?
You Can’t Have One without the Other: How Body Systems are Connected. The human body contains trillions of cells, 78 different organs and more than 60,000 miles of blood vessels if you stretched them end-to-end. Incredibly, all of these cells, vessels and organs work together to keep you alive.
What is your basis in identifying the different levels of biological organization of an organism?
The biological levels of organization of living things arranged from the simplest to most complex are: organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere.
What happens to an organism if an organ or organ system does not function properly?
All of the organ systems of the body work together to maintain homeostasis of the organism. If homeostasis fails, death or disease may result.
How do tissues work together as organs?
When different types of tissues are organized together to perform a complex function, it’s called an organ. The heart is an organ. It has muscle tissue, connective tissue, and nerve tissue all working together to pump blood.
What is the difference between cell tissue organ organ system and organism?
Levels of Organization: Molecules form cells. Cells form tissues, and tissues form organs. Organs that fulfill related functions are called organ systems. An organism is made up of interconnected organ systems.
Why is it important for the organ system of plants to work together?
In plants, just as in animals, similar cells working together form a tissue. When different types of tissues work together to perform a unique function, they form an organ; organs working together form organ systems. The root system anchors the plant while absorbing water and minerals from the soil.
What are the plant organs and their functions?
In plants, each organ has several jobs, or functions.
- Roots keep a plant in the ground. They also take in water and nutrients from the soil.
- Leaves absorb sunlight, and make food for the plant by photosynthesis.
- The stem supports the leaves and flowers.
- Reproductive organs allow a plant to produce new plants.
