Hematology
Hematology is the medical specialty concerned with disorders related to the transportation of oxygen and nutrients to the body, as it focuses on blood and blood-producing organs like the bone marrow. This specialty deals with conditions such as anemia, blood clotting disorders, and diseases of the blood vessels that can affect oxygen and nutrient delivery.

Examples: Rickets, Scurvy, Goiter, Osteoporosis, Beriberi, Kwashiorkor, and some types of anemia. These are diseases or disorders that are caused by lack of essential nutrients.
The circulatory system, consisting of the heart, blood vessels, and blood, is used for the transportation of nutrients throughout the body. Nutrients are absorbed in the intestines and transported via the bloodstream to cells where they are needed for energy, growth, and repair.
I have included a link that points out some of the vitamins and nutrients that men should be concerned about.
The vascular tissue in the flower, specifically the phloem, is responsible for transporting sugars and nutrients from the leaves to the rest of the plant.
Moss obtains nutrients for its growth and survival through its leaves, which can absorb water and nutrients from the air and surrounding environment. This process is known as osmosis, where the moss takes in essential nutrients like nitrogen and phosphorus to support its growth.
No, connective tissue is primarily concerned with providing structural support, connecting and anchoring various tissues and organs in the body, and serving as a medium for transportation of nutrients and waste products. Some types of connective tissue, like adipose tissue, can also store energy. Secretion is a function typically associated with epithelial tissue.
I'm assuming you're talking about menstrual periods, despite the "periodic table" classification. You probably have a hormone disorder, which can be caused by many reasons. One prominent reason is in those with food disorders. Those with food disorders are those that are either bullemic or anorexic because the lack of nutrients in the blood can cause those with eating disorders to miss their periods on account of no nutrients to replenish the blood, which in turn does not replenish the brain, and the brain sends mixed messages to the other systems in the body because it is not getting the nutrients it needs. Also, any hormone disorders, where a woman has either too much or too little of estrogren, progesterone, or testosterone can cause a woman to miss her period.
