During systole of ventricle
From which part of the alimentary canal does chemical digestion begins?
Atrial natriuretic factor
The atrial natriuretic hormone (ANP) is a cardiac hormone in which genes and receptors are widely present in the body. Its main function is to lower blood pressure and to control electrolyte homeostasis. So the correct option is 'decrease blood pressure'.
Kidney has neurons for the digestive function.
Which of the following sequences is truly a systemic circulation pathway?
Which is the characteristic of heterotrophs?
1. Autotrophs are the organisms that prepare their own food, whereas, heterotrophs are the organisms that are dependent on other organisms for food.
2. Autotrophs have chlorophyll, whereas, heterotrophs lack chlorophyll.
The heart is covered by
Autotrophs and heterotrophs differ in
Hence, autotrophs obtain carbon from inorganic sources like carbon dioxide.
Heterotrophs cannot synthesize their own food and are dependent on other organisms for nutrition.
Hence, heterotrophs obtain reduced carbon in the form of carbohydrates from other organisms.
Lymph can be defined as
Lymph is a colorless fluid, containing specialized lymphocytes, which are responsible for the immune responses of the body.
Lymph is also an important carrier for nutrients, hormones, etc. Fats are absorbed through lymph in the lacteals present in the intestinal villi. Lymph lacks RBCs and platelets.
Lymph contains white blood cells. So option (d) is correct.
Minerals absorbed by roots move to the leaf through
The process of taking in CO2 by plants and releasing O2 is component of
Choose the correct answer from the alternatives given: The respiratory centre, which regulates respiration in humans is located in ______________.
Which of the following part/s of the human digestive system involves both chemical and mechanical ways of digestion?
b) Stomach: It is the digestive part which is J shaped and store food around 4-5 hours and churn the food with churning movement and acid and pepsinogen mix with the food which forms pepsin which helps in the digestion of protein.
c) Mouth: It is the first part of the digestive tract where food is broken down into a paste by teeth and digestion of starch starts here with the help of enzyme salivary amylase. So the correct option is 'Both B and C'.
